In 1075 Stigand transferred the see. About thirteen years later the new cathedral building appears to have been begun under Ralph, and in another twenty years so much had been finished as would allow him to see it dedicated. It is probable that before this ceremony was performed a considerable portion of the eastern section of the work was finished; for in accordance with a general custom with the mediæval church builders, this part would have been that first begun. But how much of it was ready for use? The sanctuary and presbytery, or choir, with its necessary structural appendages, no doubt first appeared. It may be that no more than this was ready when the dedication took place. But it is not possible to say with any authority what actually was finished. Nevertheless, the character of the building itself explains the course in which the structure was developed. After the first fire, in 1114, the work steadily continued, and it is possible that before that mishap occurred, certain other parts had been begun, if not finished. The remains of the original nave still present distinct evidence to show that it was, with the aisles, built in two sections; and these, although they appear at first to be alike, prove upon closer examination that the four bays towards the west are of a later date than those other four eastward. Now it is not essential that we should know exactly how much of the building was finished by a certain year, or what stage towards completion had been reached at any particular time; it is sufficient at present that we should be able to indicate the general trend of the operations,--and this would suggest the conclusion that, having prepared so much as was necessary about the chancel, the builders went on busily, after the dedication, to deal with the transept and the nave. Then followed those four early bays of the nave which are nearest to the east. It is quite safe to assume upon various grounds that the work had been carried on successfully up to this stage early in the twelfth century; but neither the documentary evidence available, nor the condition of the fabric, enables us to venture more than this surmise concerning its condition at that time. Between 1114 and the time of the second and serious fire in 1187, the remainder of the whole scheme planned a hundred years before was apparently finished.
